Abstract—The impact of emissions from the Siberian Chemical Plant (Tomsk oblast) on reproduction and
embryonic development of the fieldfare was studied. Bird abundance, clutch size, and egg volume in the impact
and background (control) zones were similar, but partial brood mortality in the impact zone proved to be sig-
nificantly higher, and the frequency of embryonic pathologies (including developmental abnormalities) was
also several times higher than in the control.
